摘要
Ad hoc按需距离矢量(AODV)路由协议在路由发现和维护过程中的广播会导致大量数据包从源节点发送到目的节点失败。以AODV的路线发现为重点，进行了优化重播的研究。在本研究中，引入了中间节点活动路由的生命周期比LR (lifetime ratio)，以增加不成功数据包的发送数量。仿真结果表明，与标准AODV相比，该路由协议在分组传输方面有所改进。性能指标是通过改变节点数量和速度来衡量的。omnet++用于模拟指标的性能。
Increasing packet delivery in Ad Hoc On-Demand Distance Vector (AODV) routing protocol
Broadcasting in the route discovery and the route maintenance of Ad hoc On-demand Distance Vector (AODV) routing protocol provokes a high number of unsuccessful packets deliveries from the source nodes to the destination nodes. Studies have been undertaken to optimize the rebroadcast focused on the route discovery of the AODV. In this study, lifetime ratio (LR) of the active route for the intermediate node is introduced to increase the number of unsuccessful packets delivery. Simulation results focused on the improvement of the packet delivery in the routing protocol compared to standard AODV. The performance metrics are measured by varying the number of nodes and the speeds. The OMNET++ is used to simulate the performance of the metrics.
